GEORGE P. WIGGI NTON, F KALAMAZOO, MICHIGAN, ASSIGNOR TO KALAMAZOO LOOSE LEAF BINDER COMPANY, OF KALAMAZOO, MICHIGAN.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application filed March 3, 1913. Serial No. 751,916.

To all whom it may concern:

Be it known that I, GEORGE P. WIGGIN- ToN,,a citizen of the United States, residing.

I temporary binders or loose sheet holders.

The main objects of this invention are: First, to provide in an improved temporary binder or loose sheet holder of the post type,

an improved binding post. Second, to provide in a temporary hinder or loose sheet holder of the post type, an improved securing means for the adjustable binding member. Third, to provide an improved temporary binder or loose sheet holder which is very simple and economical in structure and at the same time, one which is efiective for the purpose and simple in operation.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearlys defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I isa plan view of a structure embodying the features of my invention. Fig. II is an enlarged detail longitudinal section on a line corresponding to line 22 of Fig. I. Fig. III is an enlarged detail horizontal section on a line corresponding to line 3-3 of Fig. II. FigIV is an enlarged detail view partially in vertical section, on a line corresponding to line 4-4 of Fig. I. Fig. V is a detail view of one of the sheets 12.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the structure illustrated is provided with a cover or back member 1, to which the post support binding member 2 is connected by the flexible hinge 3. The posts 4 are formed of loops of wire, the side members of the loops being parallel. The posts are supported by riveting the ends of their side members into the support member 2. The inner edges of the side members of the posts are preferably notched at 5 to receive the securing memhers (l. The clamping member 7 is provided with slots 8 adapted to receive the posts. The securing members 6 are longitudinally slotted at 9 to engage the pin 10 on the clamping member whereby they are slidably supported thereon to slide between the side members of the posts and into engagement with the notches thereof. The notches 8 are of such length as to be a sliding fit with the post and when the securing members are wedged between the side members of the posts, the side members of the posts engage the ends of the slots 8, thus limiting the spring of the posts and also securing a clutching engagement of the post with the binding member 7. The structure is quite satisfactory with the notches 5 omitted, but with these notches present, no particular care in the adjustment of the securing members is required as the parts are eit'ectively retained even though they be only partially engaged. The securing members are provided with finger pieces 11 at their outer ends.

My improved binder is especially designed by me as a transfer binder for holding sheets or leaves, as 12, having T-shaped slots 18 therein, such sheets being especially adapted for use in structures in which the binding strips are flat as in my Patent #1,001,t89, issued August 22, 1911. My

improved binder is, however, desirable for general use where it is desired to bind leaves having slotlike openings therein.

I have illustrated and described my improvements in a simple and practical structure. I have not attempted to illustrate or describe various modifications which I contemplate, as I believe the disclosure made will enable those skilled in the art to which my invention relates, to adapt or embody the same as conditions may require. I desire, however, to be understood as claiming my improvements specifically in the form illustrated as well as broadly within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a temporary binder, the combination of the post support, a binding post formed of a loop of wire mounted on said support, the inner edges of the side members of the post being notched, a binding member slotted to receive said post, a longitudinally slotted wedge-shaped securing member, and

, a pin on said binding member engaging the slot of said securing member, whereby it is supported to slide between the side members of the post into engagement with the notches thereof.

2. In a temporary binder, the combination of the post support, a binding post formed of a loop of wire mounted on said support, a binding member slotted to receive said post,

I a longitudinally slotted wedge-shaped securpost, and a securing member mounted on said binding member to be engaged between the side members of the post.

4. In a temporary binder, the combination of a post support, a binding post formed of a loop of wire mounted on sand support, and a binding member adjustably associated with said post and provided with securing means adapted to engage between the side members of the post.

5. In a temporary binder, the combination of the post support, a loop-like binding post mounted on said support, and a binding member adjustably associated with said post and provided with securing means adapted to engage between the side members of the p In Witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
